Santa Clara County: Grid Operator Calls for Conservation after Substation Incident

That includes a commitment from PG&E to keeping facilities secure so that customers are provided safe and reliable electric service.

Here is the Original Story that was Posted at 1 p.m.:

California’s grid operator is calling for residents in Northern California, and especially in Santa Clara County, to conserve electricity after numerous gunshots caused extensive damage to a PG&E substation earlier today (April 16).

The California Independent System Operator has issued a Flex Alert and is asking residents to reduce their electricity usage by taking the following actions through midnight:

  • Turn off unnecessary lights
  • Turn off your thermostat
  • Power down unnecessary appliances and other devices.
  • Put off tasks like vacuuming, laundry, dishwashing and computer time, if possible.

Early this morning, numerous gunshots caused extensive damage to the Metcalf Transmission Substation south of San Jose. The Santa Clara County Sheriff’s Department is leading the investigation.

PG&E is assessing the damage and might take additional equipment at the substation out of service.

The incident did result in an oil leak and PG&E’s environmental team is working with local agencies to address the leak. Transformer oil is a highly refined mineral oil that is stable at high temperature and has excellent electric insulating properties.

The substation is located off Metcalf Road between Highway 101 and Monterey Road.

No customers have lost power as a result of this incident.

PG&E’s Twitter feed is providing frequent updates on the situation.
